In the field of international relations, a client state, is a state that is economically, politically, and militarily subordinated to a more powerful controlling state. [1] Alternative terms for a client state are satellite state, associated state, and dominion, condominium, self-governing colony, and neo-colony, protectorate, vassal state, puppet state, and tributary state.
Ancient states such as Persia and Parthia, Greek city-states, Ancient China and Ancient Rome sometimes created client states by making the leaders of that state subservient, having to provide tribute and soldiers. Classical Athens, for example, forced weaker states into the Delian League and in some cases imposed democratic governments on them. Later, Philip II of Macedon similarly imposed the League of Corinth. One of the most prolific users of client states was Republican Rome [2] [3] which, instead of conquering and then absorbing into an empire, chose to make client states out of those it defeated (e.g. Demetrius of Pharos), a policy which was continued up until the 1st century BCE when it became the Roman Empire. Sometimes the client was not a former enemy but a pretender whom Rome helped, Herod the Great being a well-known example. The use of client states continued through the Middle Ages as the feudal system began to take hold.
The number of tributary or vassal states varied over time but most notable were the Khanate of Crimea, Wallachia, Moldavia, Transylvania, the Sharifate of Mecca, and the Sultanate of Aceh.

Austria-Hungary tried to make Serbia a client state in order to form a Christian opposition to the Ottoman Empire, but after the 1903 May Coup, Serbia came under the influence of Russia, which was forming a pan-Eastern Orthodox opposition to the Latin Christianity represented by the Austro-Hungarian Empire. In 1914, Russia repeatedly warned the Austria-Hungary against attacking Serbia. When it did attack, Russia mobilised its army. [4] [5] [6] Russia also wanted Bulgaria [7] and Montenegro [8] as client states.
At the time, Great Britain and Austria-Hungary both considered Serbia as a client state controlled by Russia, [9] and most historians today might call Serbia a client state.
During the Revolutionary and Napoleonic eras (1789–1815), France conquered most of western Europe and established several client states.
At first, during the French Revolutionary Wars, these states were erected as "Républiques soeurs" ("sister republics"). They were established in Italy (the Cisalpine Republic in Northern Italy and the Parthenopean Republic in Southern Italy), Greece (Îles Ioniennes), Switzerland (the Helvetic Republic and the Rhodanic Republic), and Belgium and the Netherlands (Batavian Republic).
During the First French Empire, while Napoleon I and the French Army occupied much of Europe, such states changed, and several new states were formed. The Italian republics were transformed into the Kingdom of Italy under Napoleon's direct rule in the north, and the Kingdom of Naples in the south, first under Joseph Bonaparte and later under Marshal Joachim Murat. A third state was created in the Italian Peninsula, the Kingdom of Etruria. The Batavian Republic was replaced by the Kingdom of Holland, ruled by Napoleon's third brother, Louis Bonaparte.
A total of 35 German states, all of them allies of France, seceded from the Holy Roman Empire to create the Confederation of the Rhine, a client state created to provide a buffer between France and its two largest enemies to the east, Prussia and Austria. Two of those states were Napoleonic creations: the Kingdom of Westphalia, which was controlled by Jérôme Bonaparte, the Emperor's youngest brother; and the Grand Duchy of Würzburg as was Poland, then the Duchy of Warsaw.
During the French invasion of the Iberian Peninsula, Napoleon attempted to subjugate Portugal and Spain into a client Kingdom of Spain, but the French were eventually driven out of Iberia in a costly war.
In the 20th century, France exercised a sphere of influence, or Françafrique over its former African colonies, [10] [11] and to some degree former Belgian colonies in Africa (which were also French-speaking). The term is sometimes used pejoratively, to characterise the relationship with France as neocolonial. The former colonies provide oil and minerals important to the French economy, and in some, French companies have commercial interests.
The Indian princely states were nominally sovereign entities in the British Empire and in 1947, were given a choice to either accede to independent India or Pakistan or get independence (the Nizam of Hyderabad did opt for independence but his kingdom was annexed by Indian forces in 1948). Egyptian independence in 1922 ended its brief status as a British protectorate and Iraq was made a kingdom in 1932. But in both cases, the economic and military reality did not amount to full independence, but a status where the local rulers were British clients. Other instances include Africa (e.g. Northern Nigeria under Lord Lugard), and the Unfederated Malay States; the policy of indirect rule .

The term has also been applied to states which are extremely economically dependent on a more powerful nation. The three Pacific Ocean countries associated with the United States under the Compact of Free Association (the Federated States of Micronesia, the Marshall Islands, and Palau) have been called client states.

In the late 19th century, the Empire of Japan gradually reduced Joseon Korea's status to that of a client state. In the early 20th century, this was converted to direct rule. Manchukuo, in contrast, remained a puppet state throughout World War II.

Empire of Vietnam (1945)Soviet proxy, "satellite", or client states included much of the Warsaw Pact member states whose policies were heavily influenced by Soviet military power and economic aid. Other nations with Marxist–Leninist governments were routinely criticised as being Soviet proxies as well, among them Cuba following the Cuban Revolution, the Chinese Soviet Republic, North Korea, [23] North Vietnam, South Yemen, the People's Republic of Angola, the People's Republic of Mozambique, and the Democratic Republic of Afghanistan. Within the Soviet Union itself, the Ukrainian SSR and the Byelorussian SSR, had seats at the United Nations, but were actually proper Soviet territory.
The Central Powers, also known as the Central Empires, were one of the two main coalitions that fought in World War I (1914–1918). It consisted of the German Empire, Austria-Hungary, the Ottoman Empire, and Bulgaria; this was also known as the Quadruple Alliance.
The word emperor can mean the male ruler of an empire. Empress, the female equivalent, may indicate an emperor's wife, mother/grandmother, or a woman who rules in her own right and name. Emperors are generally recognized to be of the highest monarchic honour and rank, surpassing kings. In Europe, the title of Emperor has been used since the Middle Ages, considered in those times equal or almost equal in dignity to that of Pope due to the latter's position as visible head of the Church and spiritual leader of the Catholic part of Western Europe. The emperor of Japan is the only currently reigning monarch whose title is translated into English as "Emperor".
The history of Europe is traditionally divided into four time periods: prehistoric Europe, classical antiquity, the Middle Ages, and the modern era.
The Napoleonic Wars (1803–1815) were a series of conflicts fought between the First French Empire under Napoleon (1804–1815) and a fluctuating array of European coalitions. The wars originated in political forces arising from the French Revolution (1789–1799) and from the French Revolutionary Wars (1792–1802), and produced a period of French domination over Continental Europe. The wars are categorised as seven conflicts, five named after the coalitions that fought Napoleon, plus two named for their respective theatres; the War of the Third Coalition, War of the Fourth Coalition, War of the Fifth Coalition, War of the Sixth Coalition, War of the Seventh Coalition, the Peninsular War, and the French invasion of Russia.
A puppet state, puppet régime, puppet government or dummy government is a state that is de jure independent but de facto completely dependent upon an outside power and subject to its orders. Puppet states have nominal sovereignty, except that a foreign power effectively exercises control through economic or military support. By leaving a local government in existence the outside power evades all responsibility, while at the same time successfully paralysing the local government they tolerate.
The Treaty of Amiens temporarily ended hostilities between France, the Spanish Empire, and the United Kingdom at the end of the War of the Second Coalition. It marked the end of the French Revolutionary Wars; after a short peace it set the stage for the Napoleonic Wars. Britain gave up most of its recent conquests; France was to evacuate Naples and Egypt. Britain retained Ceylon and Trinidad.
The aftermath of World War I saw far-reaching and wide-ranging cultural, economic, and social change across Europe, Asia, Africa, and even in areas outside those that were directly involved. Four empires collapsed due to the war, old countries were abolished, new ones were formed, boundaries were redrawn, international organizations were established, and many new and old ideologies took a firm hold in people's minds. World War I also had the effect of bringing political transformation to most of the principal parties involved in the conflict, transforming them into electoral democracies by bringing near-universal suffrage for the first time in history, as in Germany, Great Britain, and Turkey.
A puppet ruler is someone who holds a title that indicates they have political authority, but is loyal to or controlled by outside persons or groups. A foreign government can wield such outside control, and the puppet ruler's territory is referred to as a puppet state. Internal factors, such as non-elected officials, may also exert power over the puppet monarch. A figurehead monarch, as a source of legitimacy and perhaps divine reign, has been the used form of government in numerous circumstances and places throughout history.
In the history of the 20th century, the interwar period lasted from 11 November 1918 to 1 September 1939 – from the end of World War I to the beginning of World War II. It was relatively short, yet featured many social, political, and economic changes throughout the world. Petroleum-based energy production and associated mechanisation led to the prosperous Roaring Twenties, a time of social and economic mobility for the middle class. Automobiles, electric lighting, radio, and more became common among populations in the first world. The era's indulgences were followed by the Great Depression, an unprecedented worldwide economic downturn that severely damaged many of the world's largest economies.
A buffer state is a country geographically lying between two rival or potentially hostile great powers. Its existence can sometimes be thought to prevent conflict between them. A buffer state is sometimes a mutually agreed upon area lying between two greater powers, which is demilitarised in the sense of not hosting the armed forces of either power. The invasion of a buffer state by one of the powers surrounding it will often result in war between the powers.
The Allies, formally referred to as the United Nations from 1942, were an international military coalition formed during World War II (1939–1945) to oppose the Axis powers. Its principal members by the end of 1941 were the "Big Four" – United Kingdom, United States, Soviet Union, and China.
The Entente, or the Allies, were an international military coalition of countries led by France, the United Kingdom, Russia, the United States, Italy, and Japan against the Central Powers of Germany, Austria-Hungary, the Ottoman Empire, and Bulgaria in World War I (1914–1918).
A naval ensign is an ensign used by naval ships of various countries to denote their nationality. It can be the same or different from a country's civil ensign or state ensign.
A rump state is the remnant of a once much larger state, left with a reduced territory in the wake of secession, annexation, occupation, decolonization, or a successful coup d'état or revolution on part of its former territory. In the last case, a government stops short of going into exile because it controls part of its former territory.
The following outline is provided as an overview of and topical guide to World War I:
The First French Empire, officially the French Republic, then the French Empire after 1809 and also known as Napoleonic France, was the empire ruled by Napoleon Bonaparte, who established French hegemony over much of continental Europe at the beginning of the 19th century. It lasted from 18 May 1804 to 3 May 1814 and again briefly from 20 March 1815 to 7 July 1815, when Napoleon was exiled to St. Helena.
Military aircraft insignia are insignia applied to military aircraft to visually identify the nation or branch of military service to which the aircraft belong. Many insignia are in the form of a circular roundel or modified roundel; other shapes such as stars, crosses, squares, or triangles are also used. Insignia are often displayed on the sides of the fuselage, the upper and lower surfaces of the wings, as well as on the fin or rudder of an aircraft, although considerable variation can be found amongst different air arms and within specific air arms over time.
